The obverse design features the Mexican coat of arms, an eagle clutching a snake while it perches on a prickly pear cactus. On the outer periphery is the phrase “ESTADOS UNIDOS MEXICANOS” or as translated to english “United Mexican States”.
The reverse design features a wreath tied off with a bow at the bottom, the denomination “5C” within and year of issue at the top. All coins were minted at the Mexico City Mint and display a “Mo” mint mark just below the bow.
